    Well, you need to shock your pool... Pool School'sDefeating Algae is the place to start. Can't suggest anything more specific unless you provide some test results.

    Run your filter continuously until it has cleared it up. You may need to backwash, depending on your filter type.

    Add your pool specs to you signature as that will help people give you correct info.

    In addition to running your pump 24x7 you'll need to brush several times a day.

    By doing that we may be able to help you adjust your water so that you don't come home to a "greenie-meanie" again .

    Re: Help my pool has gone green

    You know you are done shocking when:

    You lose less than 1ppm FC overnight;
    Your CC is .5 or less;
    Your water is sparkly-clear.

    Unless those three criteria have been met, you aren't done yet....

    Signature edited to include pool information. Yes pump was on a 4 hour timer should have been running. We had a bad storm when I was gone and maybe that was part of the problem. I dont have a test kit, take water to pool store

    Re: Help my pool has gone green

    Thank God for this forum. The pool is getting better but still needs a lot of work.
    24 hours after first shocking:





    48 hours later:





    Still adding shock every 6 hours and taking water to pool store once a day.

    Re: Help my pool has gone green

    These are the latest test results. Pool is looking better but its just not getting there quick enough.

    FC - 2.5 ppm
    CC - 0.0 ppm
    TC - 2.5 ppm
    CYA - 25 ppm
    pH - 7.6

    Is there anything else I can do besides add shock and keep testing. I need a big bottle of POP.

    Keep adding more chlorine. You should not let the chlorine dip below shock value. 2.5ppm is way too low.

    I agree, keep shocking!

    It didn't turn green over night, and it's not gonna clear over night. Crack open the POP, sit back and relax! It'll be beautiful once again!

    You really need to look at getting a good test kit. It may seem like a lot of money for the full tftestkit, but it's worth every penny, easily pays for itself with just the frustration it will save you.

    Ditto to Randy's comments.

    The best investment we made in our pool is the test kit. It has saved us many, many $$ and put us in control of our pool.

    I highly recommend the TF100 from http://www.tftestkits.net. Not only is it one of the two most recommended, it is a better bang for the $$, A-1 service, and duraleigh, the owner, is always around to help with any testing issues.

    Do yourself and your pool a big favor and order one.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.
